متن کاملWire initiation critical for radiation symmetry in z-pinch-driven dynamic hohlraums.
Axial symmetry in x-ray radiation of wire-array z pinches is important for the creation of dynamic hohlraums used to compress inertial-confinement-fusion capsules. We present the first evidence that this symmetry is directly correlated with the magnitude of the negative radial electric field along the wire surface. This field (in turn) is inferred to control the initial energy deposition into t...
متن کاملHELIOS Benchmark Calculation: Radiation-Driven Capsule Implosion in Z-Pinch Dynamic Hohlraum
In this HELIOS benchmark simulation, a spherical capsule embedded in a low-density CH2 foam is imploded by an external radiation field. The parameters utilized in this benchmark simulation are taken from z-pinch-driven dynamic hohlraum experiments performed at the Z facility at Sandia National Laboratories [1]. The time-dependent hohlraum radiation field is constrained by on-axis XRD and bolome...
متن کاملSteady-state radiation ablation in the wire-array Z pinch
The mass ablation phase of a wire-array Z pinch is investigated using steady-state r , simulations. By identifying the dominant physical mechanisms governing the ablation process, a simple scaling relation is derived for the mass ablation rate ṁ with drive current I, in the case where radiation is the primary energy transport mechanism to the wire core. In order to investigate the dependence of...
متن کاملZ-pinch Driven Isentropic Compression for Inertial Fusion
The achievement of high gain with inertial fusion requires the compression of hydrogen isotopes to high density and temperatures. High densities can be achieved most efficiently by isentropic compression. This requires relatively slow pressure pulses on the order of 10-20 nanoseconds; however, the pressure profile must have the appropriate time history [J. Nuckolls et. al. Nature, 239, 139, 197...
